To display quota limit information
Display quota limit information of all the directories on which limit is set, using the following command:
# gluster volume quota VOLNAME list
For example, to view the quota limit set on test-volume:
# gluster volume quota test-volume list
Path       Hard-limit  Soft-limit   Used    Available
------------------------------------------------------
/dir        10GB        75%       0Bytes    10.0GB
/dir/dir2   20GB        90%       0Bytes    20.0GB

[shanks] We mention about listing quota on volume, however, the example output is incorrect.

should be:
# gluster volume quota test-volume list
Path       Hard-limit  Soft-limit   Used    Available
------------------------------------------------------
/           50GB        75%       0Bytes    50.0GB
/dir        10GB        75%       0Bytes    10.0GB
/dir/dir2   20GB        90%       0Bytes    20.0GB
...


...
# gluster volume quota VOLNAME list /directory name

should be

# gluster volume quota VOLNAME list /<directory name>
...


...
For example, to view the limit set on /data directory of /dir:
For example, to view the limit set on /data directory of /dir and /dir/dir2:

[shanks] unclear what the above means. What is "/data" ?
...


...
/dir   10GB          75%       0Bytes  10.0GB

should be

/dir   10.0GB          75%       0Bytes  10.0GB

[shanks] The above is true for all the examples.

The following example displays the disk usage when quota-deem-statfs is on.

[shanks] Example given is confusing. Would like to see something like:

[root@server1 ~]# gluster vol quota shanks-vol list
                  Path                   Hard-limit Soft-limit   Used  Available
--------------------------------------------------------------------------------
/                                        300.0GB       90%      11.5GB 288.5GB
/shanks/Downloads                         77.0GB       75%      11.5GB  65.5GB
[root@server1 ~]# 


when quota-deem-statfs is off (default)
server1:
[root@server1 ~]# gluster vol set shanks-vol features.quota-deem-statfs off
volume set: success
[root@server1 ~]# 

client1:
[root@localhost ~]# df -h
Filesystem                    Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root   44G  5.1G   37G  13% /
tmpfs                         3.8G   84K  3.8G   1% /dev/shm
/dev/vda1                     485M   86M  374M  19% /boot
10.70.42.214:/shanks-vol      400G   12G  389G   3% /home
[root@localhost ~]# 


when quota-deem-statfs is on
server1:
[root@server1 ~]# gluster vol set shanks-vol features.quota-deem-statfs on
volume set: success
[root@server1 ~]# 

client1:
[root@client1 ~]# df -h
Filesystem                    Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root   44G  5.1G   37G  13% /
tmpfs                         3.8G   84K  3.8G   1% /dev/shm
/dev/vda1                     485M   86M  374M  19% /boot
10.70.42.214:/shanks-vol      300G   12G  289G   4% /home
[root@localhost ~]# 

with a clear summary on what is the benefit with quota-deem-statfs being on and probably even saying that it is recommended to set this on.
